Order Product
Place a real product order from Amazon or Walmart, shipped to a US address. By default only free-shipping / Prime items are ordered (freeShipping=true): the vendor is constrained to a free-shipping offer, so shipping is $0 and can't push the charge past the cap, and an item with no free offer is rejected before payment. Set freeShipping=false to allow paid-shipping offers (a flat shipping allowance is then folded into the cap). Pay in USDC from a connected crypto wallet, or in fiat straight from a connected Airwallex balance — whichever wallet you select. You pay the listed item cost plus a tax buffer plus a service fee of $2.50 + 2%; unused headroom between the cap and the retailer's final total is refunded on the same rail you paid from. The product charge never exceeds the authorized cap. Paying from an Airwallex balance is a PREVIEW capability, available on local and dev only — no production org can hold an Airwallex connector, so the fiat rail cannot be selected there. Where it is available it needs maxTotalCents, which is then the all-in total including the service fee, and needs no wallet, chain or gas. Ideal for: automated purchasing, reorder workflows, gifting, buying supplies with crypto or fiat.
